Changes in cat behaviour after sterilisation

Sterilisation is a common and recommended procedure for cats, as it offers multiple benefits for both cat health and behaviour. However, many cat guardians wonder how their feline’s personality will change after sterilisation, and whether there are differences between males and females. We will look at the behavioural changes that can occur in both sexes and give you some tips to help cats adjust after surgery.

What is sterilisation?

Sterilisation involves the surgical removal of the reproductive organs. In females, the ovaries and sometimes the uterus are removed (ovariohysterectomy), while in males the testicles are removed (castration). This results in the disappearance of sexual behaviour and reduces the risk of certain diseases.

General behavioural changes

In both males and females, sterilisation brings about certain general changes in behaviour:

1. Reduced territorial behaviour: Cats tend to mark their territory less after being sterilised, as the urge to defend their space decreases with the lack of sex hormones.
2. Less aggression: Both male and female cats may become less aggressive after sterilisation. By eliminating reproductive hormones, cats are often less likely to fight with other cats.
3. Increased calm: Many cats become calmer and less hyperactive. This decrease in energy levels often translates into less destructive behaviour.

Male behaviour after sterilisation

Males often show a marked change in behaviour after castration, as sex hormones play an important role in their daily activities.

• Decreased marking: One of the most common problems in male cats is urine marking. After sterilisation, this behaviour is drastically reduced, which can be a relief for many households.
• Reduced fighting: Un- castrated males are often more prone to fight with other cats due to their territorial instinct. After castration, this need to compete decreases, resulting in a more peaceful cat.
• Less roaming: Unneutered males often seek to go out to find a mate, which can lead them to roam for long distances. After sterilisation, the need to explore is reduced, and males often prefer to stay closer to home.

Females behaviour after sterilisation

Females, like males, undergo significant behavioural changes after sterilisation.

• Elimination of the oestrus cycle: One of the most noticeable changes is the disappearance of the oestrus cycle. Unneutered females tend to become more vocal and demanding during heat, a behaviour that disappears completely after surgery.
• Less stress: Sterilised females tend to be less anxious and agitated, as they do not feel the biological pressure to find a mate.
• More attachment: Some sterilised females may become more affectionate and seek more companionship from their guardians, as their focus shifts from reproduction to social interaction.

Differences between males and females after sterilisation

Although both males and females show positive changes after sterilisation, there are some key differences in how these changes manifest themselves.

• Physical activity: Sterilised males tend to show a greater reduction in physical activity compared to females. This means that males may have a stronger tendency to gain weight after surgery, requiring greater attention to diet and exercise.
• Affectionate behaviour: Sterilised females tend to become more affectionate than males, although this is not a fixed rule. While sterilised males may become calmer, females tend to show a greater need for contact with their humans.

How to support your cat after sterilisation?

Once your cat has been sterilised, it is important to pay attention to your cat’s diet and lifestyle. Sterilised cats are more likely to gain weight, so a proper diet is key.

Remember that taking care of your sterilised cat’s diet is essential to avoid health problems related to being overweight. Opting for foods specifically formulated for sterilised cats, such as those we offer at Picart can help keep your feline healthy and happy.

A new start for your sterilised cat

Sterilisation not only improves the general health of cats, but also positively affects their behaviour. Both male and female cats become calmer, more affectionate and less territorial. With proper care, your sterilised cat can live a long, healthy and fulfilling life.
